Reverse charge mechanism

Sir/Madam,

Please show me some light in the following matter :

I am a FCA and working partner of a CA firm. We are going to supply data entry operators to a Corporation wholly owned by Central Government. Wheather this service will be coverred under ' Chartered Accountant's service - clause 65(105)(s) ' or ' Manpower recruitment or supply agency - clause 65(105)(k) ' for applying service tax. Wheather reverse charge mechanism will apply here?
